Universal Motor Protection Device (Numeric Relay)

These Universal Motor Protection Device (Numeric Relay) are conceptually new SCADA compatible (RS232 & RS485 Modbus RTU), reasonably priced protection devices for 3-phase AC motors. It comes in bundle with its real time monitoring/ programming software. This is the first time when a protection unit is able to perform full and effective multi-fault motor protection. The Universal Motor Protection Device (Numeric Relay) provides protection from all faults in the mains, motor performance-induced faults and internal fault conditions of motor. Application of modern microprocessor-based technology allows to use the wanted operation logic that no protection devices of domestic and foreign production can provide. Actually consumers get a bundle of products for the price of one - a voltage relay, a phase monitoring relay, an isolation monitoring relay, a current monitoring relay, a current leakage protection device, an overload/ underload protection device, an automatic reset unit with time delays, and so forth.

Mains voltage fault protection is available,
The UBZ-302 allows to set a nominal current with a high degree of accuracy before a load is thrown-on,
Unit operates on RMS current and RMS voltage.
